| Summary: | Most of the current researches are to suppress the vibration during the earthquake for the
building and always focused on either full state feedback strategies or velocity strategies. An accurate
measurement is a necessary such as displacement and the velocities of the building are difficult to
achieve directly, particularly during the seismic activity. In this study, it was proposed that the new
generation of building control concept to suppress the horizontal vibration during the earthquake by
using an active mass damper (AMD) system. The Lagrange’s, D’Alembert’s and Newton Second Law
techniques are used to derive the two dimensional mathematical model of second order differential
equation of AMD system. Four diagrams of stability analysis were used to identify the stability of
the system before making an experimental and simulation analysis. Regarding the stability analysis,
AMD system is good enough to give a positive feedback during the application of the force of
vibration. Then, by using MATLAB-SIMULINK, the model was analyzed again in an experimental
and simulation analysis. In this analysis, both of the result is reasonably closed where the correlation
is more than 95 percent, and this would give positive responses such as time response and amplitude
in order to suppress a vibration during the earthquake disaster. |
